Answer:
Impacts of suburban development on undeveloped deciduous forest and meadow ecosystems are - : loss of biodiversity , excessive land use , deforestation , degradation of air quality , increase in the amount of greenhouse gases , therefore leading to environmental loss .
Explanation:
SUBURBANIZATION -: Suburbanization is a demographic change, resulting in the creation of (sub)urban sprawl, from core urban areas to suburbs. Low-density, peripheral urban areas are increasing as a consequence of the migration of households and companies out of the city centers. (Urbanization, which signifies a demographic change from rural areas to urban centres, is inversely related to suburbanization.)
Within the central urban area, many residents of metropolitan regions work and prefer to live in satellite communities called suburbs and commute to work by car or mass transit. Others have taken advantage of advances in technology to operate from their homes.
Environmental Implications -: This can have negative effects on the community with the growth of suburbanization and the spread of individuals living outside the city. Suburbanization has been related to an increase in the mileage of automobiles, an increase in land usage, and an increase in the use of residential electricity. These suburbanization factors then induced air quality deterioration, increased use of natural resources such as water and oil, and increased quantities of greenhouse gases. This causes increased use of oil and gas as well as an increase in pollution as the use of cars to drive to and from the workplace grows. This will then cause air pollution and degrade the air quality of a region with a rise in emissions from vehicles. Suburbanization is increasing, leading to an increase in housing growth, which causes the consumption of land and land available to increase.
Help!?! With this osmosis question
Answer:
( c. ) to an area of lower concentration between sugar molecules in the bottom of a beaker.
Explanation:
"Osmosis is a process which solvent such as water in most of the cases, moves from its higher concentration to its lower concentration when two concentrations are separated by a semipermeable membrane or differentially permeable membrane. " - Naqada
"As a result of osmosis, the concentration on both sides of a membrane becomes equal. In the option c) of the question sugar molecules in the beaker is not separated by a semipermeable membrane thus osmosis will not occur." - Naqada

Calculate the final concentration of BSA in the problems below using the formula
C1*V1 = C2*V2,
where C1 and V1 are the concentration and volume of the starting solution, and C2 and V2 are the concentration and volume of the final diluted solution. Include proper units and show your work for full credit.
A. 300 ul of 5 mg/ml BSA is added to 700 ul TBS
B. 50 ul of 1.5 mg/ml BSA is mixed with 450 ul H2O and 500 ul Bradford Reagent
C. 10 ul of 1 mg/ml BSA is mixed with 990 ul TBS.
D. 10 ul of 0.1 mg/ml BSA is mixed with 990 ul TBS.
Answer:
A. [tex]C_2=1.5\frac{mg}{mL}[/tex]
B. [tex]C_2=0.075\frac{mg}{mL}[/tex]
C. [tex]C_2=0.01\frac{mg}{mL}[/tex]
D. [tex]C_2=0.001\frac{mg}{mL}[/tex]
Explanation:
Hello.
In this case, we must compute the final concentration in all the cases so we solve for it in the given equation:
[tex]C_2=\frac{C_1V_1}{V_2}[/tex]
Thus, we proceed as follows:
A. Here, the final diluted solution includes the 300 μL of the 5 mg/ml-BSA and the 700 μL of TBS.
[tex]C_2=\frac{300\mu L*5\frac{mg}{mL} }{(300+700)\mu L}\\\\C_2=1.5\frac{mg}{mL}[/tex]
B. Here, the final diluted solution includes the 50 μL of the 1.5 mg/ml-BSA, the 450 μL of water and the 500 μL of TBS.
[tex]C_2=\frac{50\mu L*1.5\frac{mg}{mL} }{(50+450+500)\mu L}\\\\C_2=0.075\frac{mg}{mL}[/tex]
C. Here, the final diluted solution includes the 10 μL of the 1 mg/ml-BSA and the 990 μL of TBS.
[tex]C_2=\frac{10\mu L*1\frac{mg}{mL} }{(10+990)\mu L}\\\\C_2=0.01\frac{mg}{mL}[/tex]
D. Here, the final diluted solution includes the 10 μL of the 0.1 mg/ml-BSA and the 990 μL of TBS.
[tex]C_2=\frac{10\mu L*0.1\frac{mg}{mL} }{(10+990)\mu L}\\\\C_2=0.001\frac{mg}{mL}[/tex]

what is not a prevention method for the milkweed bug?
Answer:
remove leaf litter and spent stallis in the fall
Explanation:
A biology student looked through a microscope and observed an Elodea cell in a drop of water and illustrated it in diagram A. He added a 10% hypertonic salt solution to the slide. He then observed the cell and illustrated the change in diagram B. What caused the change in the appearance of the cell after the salt solution was added?
More water flowed into the cell than out of the cell.
More salt flowed into the cell than out of the cell.
Lass salt flowed into the cell than out of the cell.
More water flowed out of the cell than into the cell.
Answer:
There are no diagrams in this question, however, it can be answered.
More water flowed out of the cell than into the cell.
Explanation:
According to this question, a biology student added 10% hypertonic salt solution to an Elodea cell in a drop of water. The student illustrated the changes observed in diagrams A and B. Based on the principles of OSMOSIS, which is the movement of water from a region of lower solute concentration to a region of higher solute concentration, water will flow out of the cell.
Since the solution outside the Elodea cell has more solute solute/salt concentration, water will be move down the concentration gradient from the cell into the extracellular solution. Hence, more water flowed out of the cell than into the cell.

You conduct a voltage clamp experiment in which you hold the presynaptic terminal of a glutamatergic neuron (a neuron that releases glutamate) at 0 mV. When you treat the terminal with TTX, an inward current is recorded. Which ion and ion channels are responsible for the current you observe? Group of answer choices Calcium; ligand-gated non-specific cation channels Sodium; ligand-gated non-specific cation channels Calcium; voltage-gated calcium channels Sodium; voltage-gated sodium channels Potassium; voltage-gated potassium channels
Answer:
Calcium; voltage-gated calcium channels
Explanation:
Voltage-dependent calcium channels represent a group of voltage-gated ion channels and they are recognized to be primary mediators of calcium entry induced by depolarization. These channels are localized in the membrane of excitable cells such as, for example, neuron cells. The potential difference across the membrane of neuron cells without physiological activity is named resting membrane potential. When there is no action potential, voltage-dependent calcium channels are normally closed.

What roles do species play in ecosystems?
There are some species in every ecosystem that are necessary for the other species in the system to survive. The ecosystem may not be able to continue functioning without the keystone species, which could be a small plant or a large predator.
What are keystone species ?
Scientists may argue over which organisms or plants in a given ecosystem should be called a keystone species because a keystone species does not have a formal name. The idea, according to some wildlife scientists, oversimplifies the role of a single animal or plant in intricate food webs and habitats. On the other hand, referring to a specific plant or animal as a "keystone species" in an ecosystem is one way to educate the general public about how crucial one species can be to the continued existence of numerous others.There are three sorts of cornerstone species referred to by numerous researchers: mutualists, ecosystem engineers, and predatorsThe "keystone" is regarded as one of the most crucial components in any community or arrangement. An organism that contributes to the stability of the system is known as a keystone species in any kind of ecosystem, including marine ecosystems. Ecosystems would look very different without its keystone species. If their keystone species vanished, some ecosystems might not be able to adjust to changes in the environment. That could result in the ecosystem's demise or it could allow an invasive species to take control and significantly alter the ecosystem's course.To know more about keystone species check this:
